GEORGE-s. ooxfor FITZWATERTOWN, PENNSYLVANIA, AssreNon ro EIMsELE, AND WALTER s. cox, or PHILADELPHIA, PENNSYLVANIA, TRADING As GEORGE s. cox AND BROTHER.

To all whom z'tmay concern:

'Be it known that I, GEORGE S. Cox, a citizen of the United States, residing at Fitz- Watertown, county of Montgomery, and Stateof Pennsylvan1a,have invented a new and useful Improvement in Selecting Devices for Haircloth-Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,'which form apart of this specification.- I H c The object of my invention is toprovide, in

l I a hair cloth loom, new and improved means wherebyfa plurality of picks of hair may be inserted in a single warp shed. *IIGTGilOfOlG this result has been accomplished by inserting the two picks successively by means of the usual shuttle and selector, the shed being 'heldopen'until both picks are inserted.

' turers generally confine themselves to the production ofcloth containing a single pick to each shed of warp.

The object of my inventionis to provide goods of adefinitenumber of picks to the inch to beproduced with. twice the speed heretofore attained, and the invention consists in a new and improved hair selecting.

device adapted "to perform this function. By reciprocating the warp sheds. laterally, as Well as reciprocating them vertically, in the manner well known in the art, a leno Weave willbe formed whereby the pairs of wefts will be held from slippage in the direction of the extension'of the warp, and the. pairs of picks will thus beheld in position even more firmly than in the ordinary plain woven hair Thus hair cloth, equal or superior to the ordinaryhair cloth in stiffness and other essential qualities, may be manufactured at a substantiallylower costthan ordinary hair cloth.

Generally speaking, l eifect the insertion of two picks of hairsimultaneously by pro viding aplurality of pans or movable members so operated: or connected together that Specification of Letters latent.

SELECTING DEVICE FOR HAIBCLOTH-LOOMS.

Patented June 1 1909.

they will move in unison and so arranged that they will grasp different picks of hair and have an independent movement with respect to each other to enable compensation to be had, and thus with certainty to grasp and hold a plurality of wefts notwithstanding any variation in the size of the same.

To illustrate my invention, I have illustrated two embodiments of my invention, although it will be understood that the invention can be embodied in still other specific constructions.

Figure 1 is a perspective view of one form of my improved selecting device. Fig. 2 is a plan view of the same. Fig. 3 is a perspective view of another form of selecting device embodying my invention, and also of the immediate actuating mechanism therefor. Fig. 4 is a plan view of the selecting device of Fig. 3.

Referring first to the device shown in Figs. 1 and 2: The vertically'reciprocable member or needle-holder a of the selecting device has secured to it an arm I) to which is secured an upright rod 0. The latter is adapted to be actuated from the usual slide (illustrated in Fig. 3 and hereinafter described), being thereby vertically reciprocated to bring the selecting device into and out of operative relation with the hair, as is well understood in the art.

The member a is provided with flanges d (I through which extends a bolt 6 upon which is hinged the pivotal members or pan-holdersf, f.

g is a nut engaging one end of the bolt and tightening against one of the flanges d.

Extending into or through the member a are the needles h, h, which are secured in place by means of set-screws 'L, i. Extending into or through the membersfif, are the pans 7c, 76 respectively, which are secured in position by means of set screws j. Each pan has connected to it one end of a spring Z whose other end is connected to the arm I). The pans 7b", 7c, coact with the needles h, 7?, respectively.

At their outer ends the pan-holdersf, f, are connected together by means of a pin m on one engaging a slot n in the other. This enables the two pans 7c, 7r, to have a slight vertical movement with respect to each other upon their common hinge to enable two wefts of different sizes to be grasped, one between one pan and its respective needle and the other between the other pan and needle, while it enables one of the pan-holders to be actuated by means of the other.

In the drawings, the pan-holder f is the actuating member of the pair, having secured to it the vibratory arm 0 actuated in the usual manner from the usual mechanism (illustrated in Fig. 3 and hereinafter described). I

In Figs. 3 and 4, instead of providing a single needle holder, a single reciprocable actuating rod and a single vibratory actuating arm, I make each of these members separate, the general construction being in effect two separate selectors modified to bring them into the necessary close relation and arranged to enable them to pick up different hairs. p, p, are the reciprocable needle-holding members; q, q, the needles carried thereby; r, r, the pivotal pan-holding members; 5, s, the pans carried by the panholders; t, t, the actuating springs for the pan-holders; u, u, the arms secured to the needle-holders and to which the vertically reciprocable actuating rods 2;, '0, are secured; and 'w, w, the vibratory arms secured to the pan-holders. Each pan-holder at its inner end is cut away at one side to a depth of approximately half its thickness, forming an offset a and a shoulder y, the former presenting a rounded convex end and the latter a rounded concave seat. Each corresponding needle-holder is similarly cut away and shaped at its inner end so that when the two parts are placed together, the offsets will overlap and their convex ends fit respectively against the concave seats of the shoulders. Through the overlapping offsets extends a screw 2, by means of which the engaging members are pivoted together. By means of this construction, the two separate selector elements may be brought as close together as the two connected parts of the selecting device shown in Figs-1 and 2.

In both selecting devices it is preferable that the pans should engage their holders nearer to the inner sides of the latter than to their outer sides, so as to bring the pans fairly close together in this direction. Thereby the ends of the two hairs will be, as near as possible or desirable, in alinement when presented to the nipper. The needles will of course be placed in longitudinal alinement with the pans.

To prevent one set of hair selecting contrivances (pan and needle) from picking up the same strand of hair as its companion set, I prefer to offset one set longitudinally with respect to the other set. In Figs. 1 and 2, this is effected by offsetting the pans and v needles only. In Figs. 3 and 4, the same result is obtained by offsetting the two separate elements of the selecting device.

The two-part selecting device of Figs. 3 and. 4, like the unitary selecting device of Fig. 1, is operated by means of a single actuating mechanism. This mechanism comprises a constantly rotating shaft 10 turning in a bearing 11 secured to a bracket 12 on a frame 13; a cam 14 on the shaft actuating one end of a lever 15, which is pivoted between its ends on a bracket 16 secured to the frame 13 and whose other end engages the arms w, w; a slide 17 vertically slidable in guides 18 secured to the brackets 12 and carrying at its lower end the head 19 into which extend, and to which are secured, the rods Q), o, and a crank-disk 20 carrying the link 21 attached to the slide 17. It will be understood that when this actuating mechanism is applied to the selecting device of Figs. 1 and 2, the lever 15 will actuate the single arm 0, while the slide 17 will be attached to and actuate the single rod 0.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is r 1. A selecting device for hair cloth looms comprising a plurality of pan-holders located side by side, a pan attached to each panholder, a plurality of needles cooperating respectively with the pans, means supporting the needles and to which the pan-holders are pivotally connected, and means to simultaneously vertically reciprocate both needles and to simultaneously rock both pan-holders while permitting the latter to have a movement relative to each other.

2. A selecting device for hair cloth looms comprising a plurality of pans, a plurality of needles, supporting means for the pans and supporting means for the needles, the pan supporting means and the needle supporting means being pivotally secured together, devices for reciprocating the needle-holding means, and devices for rocking the panholding means while permitting the same to have a movement relative to each other.

3. A selecting device for hair cloth looms comprising a plurality of pans, a plurality of needles coacting respectively with the pans, and devices for rocking the pans relatively to the needles while permitting the same to have a movement relative to each other.

4. A selecting device for hair cloth looms comprising a plurality of pan-holders, a pan carried by each pan-holder, needles coacting with the pans, a pivot upon which said panholders move in unison, and means to enable the panholders to have a movement relative to each other.

5. A selecting device for hair cloth looms comprising a plurality of pan-holders, a pan carried by each pan-holder, a needle holder, needles coacting with said pans, carried by said needle-holder, a pivot common to said pan-holders connecting said pan-holders and i the needle-holder, and means to enable said pan-holders to have a relative movement with respect to each other.

6. In a selecting device for hair cloth looms, a plurality of pans, needles cooperating therewith, and a pivotal connection between said pans, whereby said pans may I have a relative movement with respect to each other.

7. Ina selecting device for hair cloth looms, a pan-holder, pans upon said holder,

1 needles cooperating with said pans, and a pivotal connection between said pans whereby they may have a relative movement with said pans, and a pivotal connection between said parts, whereby each part and its carried pan may have a relative movement with respect to the other.

9. In a selecting device for hair cloth looms, a plurality of pans and a plurality of needles movably connected with the respective pans to form sets of hair selecting contrivances, one set thereof being ofiset longitudinally with respect to the adjacent set. i

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 28th day of April, 1908.
